WEST PALM BEACH, Fla. (AP) — Florida Republican Gov. Ron DeSantis signed a measure Thursday prohibiting local governments from adding fluoride to their water systems, making it the second state in the country after Utah to implement a statewide ban on the mineral.

Florida has officially become the second state to ban the use of fluoride in its public water supply, marking a major win for Health and Human Services Secretary Robert F. Kennedy Jr.

Florida Gov. Ron DeSantis on Thursday signed a bill that will stop local governments from putting fluoride in water. The bill DeSantis signed doesn’t specifically mention fluoride. Instead, it bans local governments from putting anything in the water that doesn’t help with improving water quality or reducing contaminants.
